Earthquake Engineering & Structural Dynamics
The acquisition of a flexural backbone curve for columns primarily relies on finite element analysis and experiments, of which the complexity and high cost are significant challenges. Hence, this study proposes an analytical curvature distribution model (

In the design of medium- and high-rise buildings, the reinforced concrete (RC) shear wall structure is widely used to resist seismic loading. Thus, accurately predicting the seismic demand of this structural form becomes particularly important.

Lateral load pattern in pushover analysis
Earthquake Engineering and Engineering Vibration, 2003The seismic capacity curves of three types of buildings including frame, frame-shear wall and shear wall obtained by pushover analysis under different lateral load patterns are compared with those from nonlinear time history analysis. Based on the numerical results obtained a two-phase load pattern; an inverted triangle (first mode) load pattern until ...

Simplified methods are widely used in the seismic design of underground structures, but they generally ignore the influence of vertical ground motion. This can result in unreliable design because seismic earth pressure induced by vertical ground motion ...

Pushover Analysis of GFRP Pultruded Frames
Mechanics of Composite Materials, 2015Results of a pushover analysis of GFRP pultruded frames aimed at the evaluation of their overall ductility are presented. It is assumed that the dissipation capacity of the frame structures is concentrated in joints due to their nonlinear behavior induced by progressive damage, while a brittle-elastic behavior is assumed for frame members. A two-storey

Modal Pushover Analysis for Unsymmetric Buildings
Structures Congress 2005, 2005The modal pushover analysis (MPA) procedure for estimating seismic demands is extended to unsymmetric-plan buildings. In the MPA procedure, the seismic demand due to individual terms in the modal expansion of the effective earthquake forces is determined by nonlinear static analysis using the inertia force distribution for each mode, which for ...

Adaptive upper-bound pushover analysis for high-rise moment steel frames
Structures, 2019In this paper, a new nonlinear static analysis procedure is proposed to assess the seismic performance of tall buildings, which considers both the higher modes effects as well as the progressive changes in the dynamic characteristics of structures during

Multimodal Pushover Analysis for R.C. Bridges
Applied Mechanics and Materials, 2015In recent years, Italian technical-scientific community has increased its interest on the evaluation of the seismic response of existing structures. Among this wide range of structures, reinforced concrete bridges stand out for their strategic relevance and technical complexity.

Seismic Damage Detection Using Pushover Analysis
Advanced Materials Research, 2011Inter-story drift ratio is a general damage index which is being used to detect damaged stories after severe ground motions. Since this general damage index cannot detect damaged elements also the severity of imposed damages on elements, a new real-time seismic damage detection method base on artificial neural networks was proposed to overcome this ...
